Autor: Irene E. Sille, Diego E. Pissinis, Natalia S. Fagali, Fiorela Ghilini, María Noel Urrutia, Patricia L. Schilardi

Publikováno v: Pathogens, Vol 12, Iss 2, p 202 (2023)

Arthroplasty is a highly successful treatment to restore the function of a joint. The contamination of the implant via bacterial adhesion is the first step toward the development of device-associated infections. The emerging concern about antimicrobi

Models to study photoinduced multiple proton coupled electron transfer processes

Autor: Ana L. Moore, Emmanuel Odella, Paul A. Liddell, Walter Damián Guerra, María Noel Urrutia, Thomas A. Moore

Publikováno v: Journal of Porphyrins and Phthalocyanines. 25:674-682

In water-oxidizing photosynthetic organisms, excitation of the reaction-center chlorophylls (P680) triggers a cascade of electron and proton transfer reactions that establish charge separation across the membrane and proton-motive force. An early oxi

Pterins are natural products that can photosensitize the oxidation of DNA, proteins, and phospholipids. Recently, a new series of decyl-chain (i.e., lipophilic) pterins were synthesized and their photophysical properties were investigated. These decy
